针对建筑垃圾中汞污染问题，对化工、冶金、轻工、生活区、再生等5种不同来源建筑垃圾的汞含量进行分析，并评估其污染程度．研究结果表明：建筑垃圾中汞的含量范围为6．46～1542．83μg/kg ，平均值为164．97μg/kg ，化工行业建筑垃圾汞的平均含量水平大于土壤一级标准阈值，其他来源均低于土壤一级标准阈值．源于化工行业的建筑垃圾汞污染较其他行业严重，为中度污染；其他4种来源的建筑垃圾属低污染．

Construction & demolition(C&D)wastes generated from the construction ,renovation ,repair and demolition of structures were widely recognized but seldom focused on their mercury contamination . This study was initiated to characterize and assess the mercury pollution in C&D waste samples ,which came from the chemical industry ,metallurgy ,light industry ,residential ,and recycled aggregates .The re-sults illustrated that the mercury concentrate range was 6 .46 -1542 .83 μg/kg in all samples and 164 .97μg/kg as average .The average mercury concentration of chemical industry was above STVHM-Level-Ⅰ(standard threshold values of heavy metals of environmental quality standard for soils in China )w hile oth-ers were below it .Chemical industrial samples defined as medium level pollution in the single factor evalua-tion endures a much more severe contamination than samples from other sources which were defined as non-polluted .
